While Rebel and Union soldiers still fought it out with bayonets and cannons, a Confederate designer had the foresight to imagine flying machines attacking Northern armies. He couldn’t implement his vision during the war, and the plans disappeared into history, until resurfacing at a rare book dealer’s shop 150 years later.

Now those rediscovered designs have found their way to the auction block, providing a glimpse at how Victorian-eratechnology could have beaten the Wright Brothers to the punch.

The papers of R. Finley Hunt, a dentist with a passion for flight, describe scenarios where flying machines bombed Federal troops across Civil War battlefields. Hunt’s papers are set to go up for sale at the Space and Aviation Artifacts auction during the week of Sept. 15-22, giving one lucky collector a chance to own a piece of an alternate technological history that never came to pass.

Anyone who runs is a Yankee. Anyone who stands still is a well-disciplined Yankee.
